Ecological channel conformance evaluation index system architecture

Abstract

The invention discloses an ecological channel conformance evaluation index system architecture, and belongs to the technical field of ecological environment protection. Aiming at ecological channel evaluation, a system architecture with high guidance, operability and universality is constructed. An ecological navigation channel conformity classification sub-item index system is composed of three levels of 8-class classification indexes and 32 sub-item indexes contained in the 8-class classification indexes. The safety guarantee type, the ecological construction type, the environment coordination type, the human-water harmony type connotation and the representative index of the ecological channel are comprehensively reflected. A matched sub-item grading index condition qualitative or quantitative evaluation criterion system and a grading rule system are combined, and a clear, complete, detailed and quantifiable technical criterion system is provided. Through deeply investigating and evaluating ecological conformity index (URECI) of the channel, the ecological conformity represented by the URECI can be evaluated according to a matched ecological conformity evaluation criterion system, and complete evaluation technical tools can be provided for ecological channel construction, management and evaluation effects.

Description

technical field [0001] The invention relates to an ecological waterway conformity evaluation index system framework, which belongs to the technical field of ecological environment protection and evaluation. Background technique [0002] (1) Connotation of ecological waterway construction [0003] The construction of ecological waterways is not to simply and passively protect the ecological environment, but to consider the development needs of the river basin economy and society as a whole, to find a balance between the positive ecological and environmental benefits of waterway construction and the ecological protection that mitigates negative impacts. Scientific rectification and moderate development, rational use of natural water depth for transportation, effectively reduce energy consumption and accident probability of bulk cargo transportation, reduce environmental pollution, simultaneously promote the construction of shipping ecological civilization, and improve the ha...

[0015] 4) Zhu Kongxian, Jiang Min, Li Ligang, and Wang Jiasheng conducted a preliminary study on the hierarchical analysis and evaluation index system of ecological waterways, aiming to provide reference for construction plans, from the aspects of construction ecology, waterway ecology, shipping environmental protection, waterway sustainability and society. In five aspects of suitability, 23 evaluation indicators were established to analyze the ecology and sustainability of materials processing, construction and operation management, as well as the impressions of the drivers and passengers and the public along the waterway on the social service function, but the paper does not involve Specific indicator requirements and evaluation criteria

[0017] 6) Xu Shiguo, Shi Ruihua, Wang Guoti, and Li Hongzhuo evaluated and optimized the ecological slope protection of urban rivers. The ecological slope protection project evaluation index system constructed included cost (construction cost, maintenance cost, service life), ecological landscape (ecological protection and Restoration, hydrophilicity, coordination with the surrounding environment), construction technology (availability of materials, simplicity of technology) and 8 indicators in three aspects, and the scoring value and weight value were obtained by questionnaire survey method; the proposed ecological The target system of bank slope protection includes relevant indicators of safety evaluation, engineering structure and ecological protection, but no specific indicators are specified.
